Ok, I'm back from my cruise now and my TA was right - everything went smoothly. Other passengers had their docs in hand, so apparently because my TA is a discount agency for airline employees - sort of "no frills", I guess it was a little different for us. Anyway, when they asked for our docs I told them my TA said they were pickup. Their response was "did you fill out the online pre-boarding documentation", and I had, so it was all good. Seemed like it happens all the time to them. It was like an "e-ticket"!
